* command (command:create, command:delete, command:destroy)
(command:set), mudpy.py (command_create, command_delete)
(command_destroy, command_set): Added the admin commands create,
delete, destroy and set, as a foundation for future on-line
creation/World-building systems.

* example: Included sample data from the Example project.

* mudpy.py (Element.delete): Renamed to destroy and added a new
delete method used for removing individual facets, making them
consistent with the new admin commands.
(User.delete): Renamed to destroy for consistency with the Element
class' method names.
(User.can_run): New method acting as a rudimentary access control
system for commands flagged with an administrative bool facet in
command elements.
(command_help): Modified to filter out commands the user is
disallowed from running, and now highlights administrative command
names when they're available.
(handler_active): Standardized on command_name instead of command.
